Department of Orthodontics and Pedodontics, Faculty of Dentistry, Van Lang University, Ho Chi Minh City, Vietnam.
The reverse scan technique offers several advantages, such as improvements of accuracy and visibility of critical anatomical structures, minimizing chair time, and providing better patient comfort. This was a case report successfully employing the reverse scan technique. A 72-year-old male patient desired to restore his teeth in both jaws, as he experienced difficulty eating and had never worn dentures.

Purpose: This mini-review discusses the clinical implication of respiratory pathogens in the biofilm on acrylic resin removable dentures in the elderly.
Methods: A search was conducted using the keywords: "dentures", " acrylic resin", "biofilm", "pneumonia", "elderly", "respiratory pathogens", and "respiratory diseases" in databases PubMed/Medline, Lilacs, SciELO and textbooks between 1999 and 2024.
Results: The elderly are more susceptible to chronic diseases and/or life-threatening infections because of senescence itself and functional and degenerative alterations.
Effect of nanogold incorporation into polymethyl methacrylate denture bases on microbial activity in implant-retained mandibular overdentures.

Article Synopsis
- A clinical trial tested the effectiveness of adding nanogold particles to denture bases made of polymethyl methacrylate (PMMA) against standard acrylic bases, focusing on their impact on bacterial growth.
- Twenty-two male patients with no teeth received either traditional acrylic dentures or those enhanced with nanogold, and microbial growth was measured over time around the implants.
- Results showed that dentures with nanogold significantly reduced bacteria counts (Candida albicans, Escherichia coli, and Streptococcus mutans) at 2, 4, and 6 months compared to traditional dentures, suggesting a promising improvement in oral hygiene.
The 'Japanese paradox' of total hip arthroplasty: where are we going?
Expert Rev Med Devices

Department of Orthopaedic Surgery, Kansai Medical University, Hirakata, Osaka, Japan.
Introduction: There is a worldwide trend toward 'revisiting' cemented total hip arthroplasty (THA). In Japan, however, cemented THAs accounts for 11%, and the percentage of cemented hemiarthroplasty is estimated to be less than 10%. This review was designed to reconsider the option of cemented THA and to encourage policy changes in Japan to support the best possible care for patients.

Department of Prosthodontics, Faculty of Dentistry, Chulalongkorn University, Pathumwan, Bangkok, 10330, Thailand.
Background: The selection guideline for the implant-supported bar connectors (ISBC) of hybrid denture is lacking. This study investigated the maximum von Mises stress (vMS), stress distribution, and displacement of various geometric ISBC in mandibular hybrid dentures, as well as the maximum principal stress (σmax) in the acrylic resin part, through finite element analysis.
Methods: Four different geometric cross-sectional patterns for mandibular ISBC-L, Y, I, and Square-of equal volume, based on the "All-on-4" concept, were created.
